Blewyn, I agree that my post isn't very helpful and I apologise for being quite bold! However, I don't think your initial post is really that helpful either.
To be fair, people who are registered at Poms in Oz looking around for info about migrating to Australia surely know to differentiate between a temporay visa and a non-temporary visa. It's in the name! Also, your posts are quite aggressive too (unnecessarily so I should think).
I can see your initial post was caused by anger and disappointment, and I really feel sorry for your bad experiences. But there are many people moving to Australia and having to deal with a range of problems. It's not easy to migrate from one country to another! And nobody expects it to be easy.
As docboat said, the condition of the temporary visa should have been clear before/whilst applying, particularly after last year's changes to the visa conditions which clearly make it even harder for foreigners to move from a temporary visa onto PR.
I think we should still be grateful for the chance that we are given to work in Australia in the first place. Please note, this comment comes from someone who really, really had to struggle finding work in the first place. I also don't like being treated as 'the foreigner' on a 457 but I knew that it could be hard, and what doesn't kill me makes me stronger.
It's funny I'm saying this because I do tend to complain about Australia a lot as you may have seen from my older posts, but this 457 thing is really something we cannot do anything about, and everybody on a 457 knows what to expect. I doubt anybody planning to move to Australia on a 457 doesn't know about the risk involved!
I certainly would love to get the chance to get PR but I cannot be sure about that happening, and I've planned for that - in the worst case I have to leave Australia without even knoweing where to go to (because I'm not even a Brit so cannot 'just' go back to the UK, and I left my native country seven years ago so there's no home for me actually).
I know, I cannot buy property in Australia as yet, I live in a shitty appartment and I have to pay over 500 bucks just for private health insurance (and on top of that I have to pay for each and every doctor's visit). But I live in Australia, in a highly developed and very sunny country! What more could I want? My partner and I are working very hard to survive here, but it's a choice we made!
